Step-by-step explanation:
1.) First, you need to take the whole numbers (9 and 1) and set them aside. 
2.) Multiply the numerators from each fraction by one another. The numerators are the numbers on the top of the fraction. (Whatever you get on that will be the numerator of the answer!) 
3.) Multiply the denominators by each other as well. The denominators are the numbers on the bottom. This will be the denominator of your answer. 
4.) Now, you need to multiply your whole numbers (9 and 1) together. 
5.) Then, simplify or reduce your answer. (this can't be simplified, as it is already in its simplest form)
Your answer will be 9 1/66.
Your work should look like this in the end:

Answer:
The constant of proportionality is equal to 4
Step-by-step explanation:
The picture of the question in the attached figure
Let
y ----> the total cost in dollars
x ----> the number of bags of peanuts
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form  or
 or 
To find out the constant of proportionality, we need to take one point from the graph
take the point (1,4)
Find the value of k

substitute the value of x and the value of y 

 
        
             
        
        
        
Answer:
Therefore values of a and b are

Step-by-step explanation:
Rewrite  in the form
 in the form 
 
 
where a and b are integers, 
To Find:
a = ?
b = ?
Solution:
 ..............Given
 ..............Given
Which can be written as
 
 

Adding half coefficient of X square on both the side we get
 ...................( 1 )
 ...................( 1 )
By identity we have (A - B)² =A² - 2AB + B²
Therefore,

Substituting in equation 1 we get

Which is in the form of

On comparing we get
a = 3 and b = 2
Therefore values of a and b are
